V6 Crankshaft Info

[Blazex]

hey sorry about the following dumb question lol, hopefully someone can clear it up for me.

i got a VN V6 Series 1 (Manual with a M78 GBox) i want to put a VR Calais Motor with that Gbox what problems will i have or can i even do it?

thanks in advance.

you'll need an 8 bolt flywheel if you want to chuck a vr motor in. Otherwise youll need a s1 manual motor. S1 auto motor you'd need the crank adapter from CRS

but will the 8 bolt fly fit straight up to my gbox?

yes it will preferbly chuck in a new clutch while your at it theyre cheap. I put a s1 manual in a vp bolted straight up with 8 bolt flywheel

sweet so the fact the fact that i want to put a AUTO (VR Calais) Engine to a Manual VN S1 engine doesnt amtter or do i just get a manual S2 Motor crank?

sorry for the dumb questions..

eh nvm just RE Read first post

"The below picture is a VN Series 2-VR Crank, it can be identified by its 8 bolt rear flange that sits flush with the rear of the blocks. These cranks will all interchange both manual flywheels & auto flexplates. If you are doing an auto to manual conversion, this is by far the easiest & best one to do."

just hope my gearbox will match up perfectly lol being a M78 dont know if theirs any differences, better not be lol.

If yours are near the min standard i suggest regrind or go the plus 1's

sorry to be a pain in the ass lol but will a ECOTEC fit up to my M78 Gbox?

Did you change from a n/a to n/a V6, or did you convert a super6 to manual ?

It aways pays to have all flywheels mirror balanced to whatever came off the new engine. Whether thats a flexplate or another flywheel, as there maybe a small difference that needs correcting.

n/a v6 auto to n/a v6 manual.

Mal Wood will provide me with a billet flywheel 'with the correct balance'. But doesn't say whether the manual & auto cranks are differently balance as I discussed above. I'm still finding it difficult to get any definitive information from a non-forum source.

It would be interesting to get feedback from people who have done the conversion without mirror-balancing to see if they had vibration.

YEs it will with 8 bolt flywheel again balancing of flywheel to match flexplate would be required

n/a v6 auto to n/a v6 manual.

I have done a vp manual conversion from auto using a series 2 vn flywheel. Would have had it balanced but flexplate was destroyed( centre ripped out) It has no abnormal vibrations. Ecotecs would probably be a different story
